1. General description of the system for pH measurement in pure water
Presentation of the 9135 transmitter The 9135 pH transmitter and associated measuring sensors has been designed for measuring and continuous control of pH or redox potential (with possibility of temperature measurement) in industrial process.
An automatic control of the sensor defaults improves the preventive servicing of the measuring chain.
2 analogue outputs (0/4 – 20 mA) may be freely programmed.
Note :
The programming is displayed in 6 languages. To modify this parameter see § 4 Changing the programming language.
Four relays and RS485 are available in option.

Introduction PH Measurement
Theory
pH is the negative logarithm of the hydrogen ion activity and a measure of the acidity, or alkalinity of a solution.
pH = -log a [H+]
pH is normally measured using a glass electrode and a reference electrode.
The glass electrode acts as a transducer, converting chemical energy (the hydrogen into activity) into an electrical energy (measured in millivolts). The reaction is balanced and the electrical circuit is completed by the flow of ions from the reference solution to the solution under test.
The electrode and reference solution together develop a voltage (emf) whose magnitude depends on the type of reference electrode, the internal construction of the glass electrode, the pH of the solution and the temperature of the solution. This voltage is expressed by the Nernst equation :
E = Eo - (2.3 RT/F)xlog a[H+]
E = Eo -(slope) xlog a [H+]
Transmitter 9135 - pH measurement in pure water
Page 5
where :
E = the emf of the cell
Eo = the zero potential (isopotential) of the system : depends on the internal construction of the glass and reference electrodes
R = gas constant
T = temperature in Kelvin
a[H+] = activity of the hydrogen ion (assumed to be equivalent to the concentration of hydrogen ions)
F = Faraday constant
For every unit change in pH (or decade change in ion concentration) the emf of the electrode pair changes by 59.16 mV at 25°C. This value is known as the Nernstian slope of the electrode.
The pH electrode pair are calibrated using solutions of known and constant hydrogen ion concentration, called buffer solutions. The buffer solutions are used to calibrate both the electrode isopotential and slope.

Description of the system for pH measurement in pure water
The probe 8362 is constituted of the following elements :
1. pH Electrode (unpluggable) 2. Temperature sensor (unpluggable) 3. U-bolt 4. Earth 5. Retaining nut for the chamber 6. Measurement chamber 7. Electrodes support 8. Thread 1/8" NPT, sample input 9. Filetage 1/8" NPT, sortie échantillon
The probe 8362-1 is provided with two unpluggable cables of length 3 m, one for the pH sensor and the other for the temperature sensor. As an option, cables of 10 m and 20 m can be supplied.
Transmitter 9135 - pH measurement in pure water
Page 7
This high purity water pH sensor is specially designed for continuous in-stream pH measurement of pure and ultra-pure water.
It uses a reference electrode very similar to the measuring electrode (combined concentric electrode) in order to minimise the impedance under which the measurement is carried out.
It is made of 316L stainless steel, which protects the measurements from electrostatic (evacuation of the charges resulting from the passage of the low conductivity liquid) and magnetic disturbances.
The circulation chamber was designed without a retention zone in order to avoid any disturbance of the measurement by CO2 dissolution and by the accumulation of air bubbles or insoluble deposits (iron oxide, residues salted out by the resins).

Supply terminals blocks and relays are under the shielded plate.
Note :
Electrical connections should remain dry to ensure a proper operation of the instrument.
Check the creeping of the cables when opening the transmitter.
Il is required to use shielded cables. The shield should be linked to the main shielding.
Transmitter 9135 - pH measurement in pure water
Page 19
Main connection Electrical connection should be performed only by qualified personnel. The power supply accepts 100-240 VAC 10 %, without changes in configuration. The terminal block for power connections can be lifted from its header for easier installation.
For safety reasons, it is required to observe the precautions below :
Use a three wire mains supply cable (2 core + PE) with a cross section between 0.35 and 2 mm² (AWG 22 to 14) rated at 105°C minimum. The external cable insulation should be cut as close as possible from the terminal block.
The instrument should be connected to the power supply by means of a breaker located close to the instrument and be identified. The supply shall be fitted with an overcurrent protection device rated at 20 Amp maximum.
This breaker should switch off phase and neutral in case of electrical problems or when the user wish to service the instrument. However the power supply earth must always be connected.
Note :
Before servicing the instrument, ensure that the power supply is switched off.

4. Hydraulic connection
Preparation of system measurement (Model 8362-1) Unscrew the measure chamber. Remove the pH bulb protector boot covering the
pH bulb and rinse the bulb area with deionized water or pH buffer. Save the boot if the electrode will be stored. It is possible that air bubbles may have migrated into the pH sensitive bulb during shipment. Since the electrode is not able to function with air behind the pH bulb, gently shake the electrode downward in the same manner as a clinical thermometer to remove any trapped air bubbles.
Hydraulic connections Re-screw the measure chamber. Assemble the 1/8" NPT connections in the 8 and 9
threads, then connect the sample inlet pipe in 8 and outlet pipe in 9 (see drawing next page).
Circulate the sample and check visually through the chamber the absence of bubbles which could disturb the measurement.
Adjust the flow to about 150 ml/mn.
Flow rate and pressure The streaming potential increasing with flow velocity, it is required to adjust the sample flow rate at a rate which does not exceed the one needed to flush properly the flow cell.
The flow rate must be set between 75 ml/mn and 375 ml/mn (ideal rate 166 ml/mn).
To avoid back pressure we advise atmospheric discharge.

Notes :
The liquid should circulate from right to left (see drawing).
The flow chamber must be earth grounded to be protected from external electrical noise.
The flow chamber should never be empty to avoid electrode damage : keep the glass bulb inwater.

The temperature of the buffer solution needs to be entered only if the transmitter is operated in the manual temperature-compensation mode.
In the « automatic calibration » mode the transmitter determines the pH value according to the temperature. In the other calibration modes, the nominal pH values must always be taken into account.
For a precise calibration of the pH electrode, 2 buffer solutions are required one of which should have a pH close to the sample pH. The pH 7 buffer solution (or 6.88 à 25°C) ) is required for a first standardization and a pH 4 buffer solution (or 4.01 to 25°C) or pH 10 (or 9.22 to 25°C) is required to calibrate the electrode slope.
Choice of the calibration type Different calibration types may be selected. In the CALIBRATION menu :
Press CHOICE to select pH standard. Press Enter. Press CHOICE to select PROGRAMMING. With the right function key, choose the calibration
type.
Automatic calibration With the right function key, select the buffer type you use so that the instrument determines precisely the buffer value according to the temperature.
You have the choice between three tables : NIST, DIN 9, DIN 10 which corresponds to the standard buffer values whose value varies according to the temperature as indicated in the previous chapter dedicated to the buffer solutions.
